Or just buy your own equipment! You can spend a couple hundred bucks on a quality modem and router or combo and it'll pay for itself in less than two years, then start saving you $10 every month after that. It's been 4 years now on my current modem and nearly 5 on the router, combined they cost the same as renting equipment for 14 months... And there's no remote reprogramming bullshit to deal with.
Side note: I'm actually considering upgrading to a gigabit router, since the service I get here clocks higher than 100Mb/s even though I only signed up for 80. It's surprising because Comcast was so shitty where I lived a couple years ago, having me pay the same amount of money for less than half the speed.
